CN202652715U - A copper block brownification clamp - Google Patents

Abstract

The utility model relates to a jig for browning a copper block, which comprises a base plate, on which a plurality of blind holes matching the copper block to be browned are opened, and a plurality of through holes are opened at the bottom of the blind hole. In the utility model, the copper block to be browned is placed in the blind hole, and the copper block to be browned can pass through the horizontal browning equipment along with the fixture to brown the copper block, so as to achieve the purpose of cleaning and roughening the surface of the copper block. Effects: 1. Solve the problem that the copper block is small and cannot be browned by horizontal browning equipment. 2. Make the copper block achieve the same effect as the browning of the inner circuit board, ensuring the bonding force between the copper block and the circuit board. 3. For copper blocks of the same size, this fixture can theoretically be used unlimited times.

Description

Copper block browning fixture

technical field

The utility model relates to a clamp used in the production process of PCB boards, in particular to a clamp used in the browning process of copper blocks.

Background technique

In the production process of buried copper block circuit boards, before pressing, the inner layer circuit board needs to be browned, and the copper block also needs to be browned to clean and roughen the copper block, so that the copper block and the board can have a good Good bonding force to prevent the copper block from falling off. The copper block is embedded in the PCB board, and it must have a good bonding force with the board. After the components are pasted, it will serve as a good heat conductor.

At present, PCB board browning equipment generally uses horizontal spraying method to chemically brown the board. The inner layer circuit board is put into the horizontal transmission roller.

Because the copper block is small, the copper block cannot be browned through the horizontal browning line. It cannot pass through the horizontal browning line like the circuit board. If it is not browned, it will affect the bonding force between the copper block and the board, and even cause it to fall off. The risk of affecting the function of the circuit board.

Utility model content

In order to overcome the deficiencies of the prior art, the purpose of this utility model is to propose a copper block browning fixture, which can make the copper block pass through the horizontal browning equipment.

In order to achieve the above object, the technical scheme adopted in the utility model is as follows:

The copper block browning jig includes a base plate, on which a plurality of blind holes matching the copper block to be browned are opened, and a plurality of through holes are opened at the bottom of the blind holes.

As a preferred structure, a plurality of through holes are arranged along the length direction of the blind holes.

As a preferred structure, the shape of the through hole is a rectangle.

As a preferred structure, a plurality of blind holes are arranged in a matrix.

The utility model has the following beneficial effects:

Place the copper block to be browned in the blind hole, and the copper block to be browned can pass through the horizontal browning equipment with the fixture to brown the copper block to achieve the purpose of cleaning and roughening the surface of the copper block.

1. Solve the problem that the copper block is small and cannot be browned by horizontal browning equipment.

2. Make the copper block achieve the same effect as the browning of the inner circuit board, ensuring the bonding force between the copper block and the circuit board.

3. For copper blocks of the same size, this fixture can theoretically be used unlimited times.

Description of drawings

Fig. 1 is the structural representation of the copper block browning fixture of preferred embodiment of the present invention;

Fig. 2 is a cross-sectional view along line A-A of Fig. 1 .

Detailed ways

In the following, the utility model will be further described in conjunction with the accompanying drawings and specific embodiments, so as to understand more clearly the technical idea claimed by the utility model.

As shown in Figures 1 and 2, the copper block browning fixture includes a substrate 1, and a plurality of blind holes 2 matching the copper block 100 to be browned are provided on the substrate 1, and the bottom of the blind hole 2 A plurality of through holes 3 are opened. A plurality of through holes 3 are arranged along the length direction of the blind hole 2 . The shape of the through hole 3 in this embodiment is a rectangle. A plurality of blind holes 2 are basically arranged in a matrix.

As shown in Figure 2, when in use, the copper block 100 to be browned is placed in the blind hole 2, and then the substrate 1 is placed on the horizontal browning equipment, and the copper block 100 to be browned is placed on the substrate 1 like a circuit board Likewise, the browning process is done on horizontal browning equipment.

For those skilled in the art, various other corresponding changes and modifications can be made according to the technical solutions and ideas described above, and all these changes and modifications should fall within the protection scope of the claims of the present invention .

Claims (4)
